Flash Program Subroutine Type 2
This routine will wait until Flash programming is completed before the user code can
continue its execution. Therefore, background programming is not supported. This type
of routine can be used to program the Flash bank where the user code is in execution.
The Flash cannot be in both program mode and read mode at the same time. It can also
be used for programming the Flash bank where the interrupt vectors are defined as
interrupts cannot be handled when the Flash is in program mode.
Note: For the Flash programming of XC864 device, Flash Program Subroutine Type 2
